✅ KEX (Potassium Ethyl Xanthate) 

KEX (Potassium Ethyl Xanthate) is a selective sulfide flotation collector with moderate collecting strength and excellent performance in copper, lead, and partial zinc flotation circuits.
As the potassium salt of ethyl xanthate, KEX offers faster dissolution, improved dispersion, and stronger surface activity than its sodium equivalent (SEX), making it particularly effective in operations requiring enhanced selectivity and cleaner concentrates.

Known for its controlled collecting power and low pyrite activation, KEX is well suited for flotation plants where grade optimization, reduced reagent consumption, and stable froth characteristics are critical.

Engineered for selective metallurgical response, KEX provides:
• Moderate collecting strength with high mineral selectivity
• Less pyrite activation compared to stronger xanthates
• Fast dissolution and improved dispersion in flotation slurry
• Cleaner concentrate grade in selective flotation circuits
• Excellent performance in copper and lead ores
• Stable kinetics in rougher and cleaner stages
• Cost-efficient operation in low-to-medium sulfide ores

KEX is commonly applied in:
• copper flotation (chalcopyrite, bornite)
• lead flotation (galena)
• zinc flotation in selective circuits (after CuSO₄ activation)
• polymetallic deposits requiring controlled flotation
• cleaner-stage flotation requiring high selectivity
